MCARTHUR MATCHER 2 Sheets-Sheet Filed Jan. 26, 1928 MATCHER Filed Jan. 26, 1928 2 Sheets-Sheet .Nwwwg Patented Dec. 17, 1929 'UNITED STATES PATENT OFFICE ARTHUR R. lNICARTI-IUR, OF GARY, INDIANA, ASSIGNOR T0 AMERIGAN SHEET AND TIN PLATE COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION 0F NEW JERSEY MATCHER -Applcation filed January 26, 1928.

This invention relates to sheet and plate handling apparatus and while not limited thereto relates more particularly to a combined matching and conveying apparatus located between a shearing apparatus and sheet doubler.

In the manufacture of sheets or light gage plates by some lmethods it is the practice to first roll a long strip of metal and then to shear this strip up into relatively short lengths or sheets. The sheets thus formed are then matched into pairs and doubled, forming packs which are reheated and again rolled to reduce their gage. n

The present invention has for its obgect the provision of a novel conveying 'table' and matcher or sheet receiving mechanism `adapted to receive and hold the sheared sheets until two are positioned, one on top of the other, or matched and then to lower the matched sheets onto the conveying table whiclrwill convey them onto the doubling mechanism. K

Another object is to provide the novel construction, design and combination of apparatus hereinafter described in detail and illusstrate-d in the accompanying drawings:

In the drawingsc Figure 1 is a side elevation partlv in section showing a yshearing apparatus, conveying table and matcher, and doubler assembled in accordance with vand embodying this inven-` tion.

Figure 2 is a plan thereof. n

Figure 3 is a transverse section on the line III-III of Figure 1.

Referring more particularly to the drawings'the letter A designates the shearing apparatus as a whole which may b e of any standard design but is shown as having a plurality ofv quick feed rollers 2, for feeding the 'strip to be sheared through the shear, a pair of shear blades or knives 3 and 4, and a pair Iof pinch rollers 5 beyond the shear blades for conveying the sheared sheets onto theA matcher (to be described).

The doubler is of the standardroll type and is only indicated generally on the drawings. The doubler is designated generally by the letter B and has the lusual doubling .blade or knife 6 and doubling rolls 7.

Serial No. 249,648.

The letter C designates the conveying table A as a .whole which is mounted between the shearing apparatus A and doubler B.

The conveying table C is of the disk roller beams 9 which support a plurality of bearings 12 in which the shafts 13 carrying con* veying roller disks 14 are journaled.

The shafts 13 are extended beyond the bearings'12 at one side of the bed 8 and have sprockets 15 mounted thereon which are connected by a drive chain 16.

One of the shafts 13 is extended beyond the bearing 12 at the side of the frame opposite from the sprockets 15 and is connected bv a standard reduction gear assembly 17 with the armature shaft of a motor 18.

A feed out pinch roller stand 19 is provided at the discharge or doubler end of the table C and the pinch rollers 2O and 21 are journaled therein. The lower roller 21 is provided with a gear 22 which is in mesh with a pinionp23 on the armature shaft 24 of a motor 25. The pinch rollers 20 and 21 are adapted to feed the matched sheets fromthe table C onto the doubler B.

A pair of side guide,V plates 26 are mounted at opposite sides of the table to guide the shea-red sheets as they are conveyed along the table C.

A matching frame D is provided for receiving the sheets as they are delivered over the table C by the pinch rollers 5 of the shear. The matching frame D comprises a pair of side arms 28 secured to a shaft 29 journaled in bearings 30 on the shear. The arms 28 eX- tend over the conveying table C and are positioned so as to fit between the disks 14 of the conveying table when they are in their lowered position. The side arms 28 are connected y p the conveyor table bed 8 and has its plungerAV 36 connected' to one of the transverse members 32 of the matching frame. Fluid is adapted,l

to enter the opposite ends of the cylinder through conduits 37 and 38 leading `.from4 a four-way valve 39` positioned adjacent the shear.

rI'he conduits 37 and 38 are connected to the cylinder 35 by short lengths of Hexible conduits 4 0 and 40 so as to permit cylinder 85 to flex when the matcher is raised or lowered. l

The matching frame D is normally held in its uppermost position and is lowered only when twoiplates or sheets are matched on the frame, so as to deliverthe matched sheets onto thelconv'eying rollers of the table` C.

While I have' shown and described the matching'lframe D as being pivotally sup ported by the shaft 29, jou'rnaled in bearings 3() on the shear, it will be understood that I do not wish to be limited to'this specific constructionsince, yif desired, or found necessary, the matcher frame may have its position reversed and the shaft 29 may be mounted invbearings on'the doubler B.v It may be particularly desirable toreverse the position of the matcher mounting in some instances in order that the highest end of the matcher will rbe l'positioned next to. the shear and, therefore,^will receive the 'cut sheets with ay minimum ofy drop. In operation, thei'shear operator'willmake certain that the matching' frame' Dis in its uppermost position. v He will then 'operate the shearingappar'atus A to shear'oif` a length of strip comprising one sheet which will be fed out onto the matching frame D, and operate the shearing' apparatus ,again to shear off alength of strip comprisinga second sheet which will be fed out on top ofthe first sheet supported on the'raised matching frame D, thus `forming a pair of matched'sheets. The operatorwill now operate the valve' 39 to admit Huid under pressure above the 'plungeiiofvthe cylinder 35 and exhaust the fln'ifd from belowfthe plunger, thereby lowering the matching frame D to its lower posiL tion below the upperplane lof the .conveying table' C soas tobring the matched sheets into engagement with the disks lil ofthe conveying table and permit said disksto convey said matched' sheets' forward i'nto the bite of the pinch rollers'20 and 21, which in turn will feed the matched sheets onto the doubler BT After the matched sheets areconveyed from While I have shown andldescrbed cie -embodimentot invention. it will be understood that I do not wish to belirnited thereto since various modilications may be made without departing from the scope of my.-inver'it'ion tls-described in the appended claims.
